These can be determined dynamically as follows (quoted from Wyman):
% nslookup | egrep sw-wic | egrep -v -- -u server moe ls 255.168.192.in-addr.arpa exit 1 host = sw-wic-116.rice.edu 3 host = sw-wic-131.rice.edu 6 host = sw-wic-141b.rice.edu 8 host = sw-wic-216.rice.edu 10 host = sw-wic-230b.rice.edu 11 host = sw-wic-241b.rice.edu 12 host = sw-wic-316.rice.edu 13 host = sw-wic-330b.rice.edu 16 host = sw-wic-341b.rice.edu 17 host = sw-wic-416.rice.edu 18 host = sw-wic-430b.rice.edu 19 host = sw-wic-441b.rice.edu %
